Since installing Catalina yesterday, multiple crashes from userspace watchdog timeout

Since I installed Catalina yesterday, I have had around five crashes with the error:

panic(cpu 6 caller 0xffffff7f8879cad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds

Any solutions. iMac Pro had been operating fine before update. Only apps running at the time were Chrome and TimeMachine backing up to a Drobo 5N2 (plus of course background apps like Google Backup and Sync, Dropbox, etc).

This happens to me reliably when i have an external monitor connected though a docking station and system is idle. If i have a video or other non static content displaying on the external monitor, my MacBook Pro I9 does not crash. This is new for Catalina and same configuration did not crash on Mojave. Need a fix...

And now after trying the looping video playing in VLC, it crashed once again after 5 hours.

Hi do you have a docking station plugged in with devices like audio attached to it?

Its only a workaround but overnight sleeps on a mac that boots in seconds is not really necessary.

Sure, I've thought of that but it's not really the point. Plus it's the difference between 30-45 seconds and 3 seconds. But the main point is that this should not be happening at all.

If its the difference between 30 seconds or a crash I would take the 30 seconds.

The thread really died down since 10.15.7 so I’m surprised you still have the problem.
